[U-Boot-Users] How to change bootdelay?If I set bootdelay=0

[dalalilala hellokity]

Hi,

It is so unwise..... 
 
I set the env "bootdelay=0" 
Boot more quickly, everything seem like perfect. 
But, I can't hit any key to stop autoboot. 
 
Who knows how can I do? 
I really want to hit any key to stop autoboot!!!! 
 
Thanks in advance

That's simple. You have to define "CONFIG_ZERO_BOOTDELAY_CHECK" in your board 
configuration file.

Best regards,

This does not help in your actual situation, but could prevent you
from running into this problem again:

Set CONFIG_ZERO_BOOTDELAY_CHECK in your U-Boot 
configuration and the autoboot process could be stopped even
if "bootdelay" is set to 0.

One way is to delete your environement variables from flash/eeprom.
Then the compiled in default values are used (and the default value
of "bootdelay" shouldn't be "0") and you could stop autoboot. This 
of course requires, that you could write to your flash/eeprom (e. g.
with a debugger, or from a running Linux system, ...).

Regards,
Martin

Sorry about I am a newbie

I haven't modify the u-boot source code,
just "make distclean omap5912osk_config dep all" to build u-boot.bin
and use tftp to reflash.

Everything is OK!

But I "setenv bootdelay 0" and then "saveenv" in u-boot prompt.

I don't know how to reburn u-boot directly.

My board is omap5912 with spectrum digital JTAG(XDS510 USB)
I have re-burn u-boot using osk5912-uboot-1.1.1.out through CCS, but it doesn't erase the parameter.
So u-boot still start with bootdelay=0.
I also have CCS to fill parameter block in memory(0x00020000-0x0003ffff), but it seems like be protected.

So........
How can I do?

Thanks everybody

Could you teach me how to use TI CCS with SPECTRUM Digital XDS510 USB TAG to erase the specific sector?

My step:
CCS->Open->ARM->Edit->Memory->Fill
But useless all the time...

Earnestly ask to help

I have wrote program to erase the parameter sector:

For OMAP5912 OSK, using TI CCS with SPECTRUM Digital XDS510.

1)
Set JP3 in the 1-2 position

2)Code (Use c:\ti\boards\osk5912\examples\led as templet)
#include "stdio.h"
#include "osk5912.h"
#include "osk5912_flash.h"

/*
 *  Run erase Flash fome 0x0C020000 to 0x0C03FFFF.
 */
void main( )
{
    /* Initialize Flash */ 
    OSK5912_FLASH_init( );

    /* Erase Flash */ 
    printf( "     Erasing Flash ( please wait )\n" );
    printf( "     Erasing fome 0x0C020000 to 0x0C03FFFF\n" );
    OSK5912_FLASH_erase( OSK5912_FLASH_BASE+OSK5912_FLASH_PAGESIZE, OSK5912_FLASH_PAGESIZE );
	printf( "     Erasing Flash OK!! \n" );
}

3)Set JP3 in the 2-3 position

4)
U-Boot 1.1.1 (Aug  4 2005 - 10:41:25)

U-Boot code: 11080000 -> 11095DD4  BSS: -> 1109A5A4
RAM Configuration:
Bank #0: 10000000 32 MB
Micron StrataFlash MT28F128J3 device initialized
Flash: 32 MB
*** Warning - bad CRC, using default environment

In:    serial
Out:   serial
Err:   serial
OMAP5912 OSK #

If you're able to boot Linux you might be able to change U-Boot 
variables from withing Linux. See DULG Chapter 14.3.26.
